LAM P-HANGER.

SPECIFICATION forming part of Letters Patent No. 684,264, dated October8, 1901.

Application tiled January I2, 1901. Serial No. 42,998. (No model.)

turned in any direction and held at any de-V sired angle between that ofthe axia-l line with its base and a substantially right angle to itsbase, thus providing a device or hanger particularly adapted for use inbarbershops, dentists offices, workshops, and the like.

I will describe a lamp-hanger embodying my invention and then point outthe novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a longitudinal section ofa hanger embodying my invention.Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is a partialsection and partial elevation of telescopic tubes employed, and Fig..tis a section on the line 4 l of Fig. 1.

The hanger or support comprises a tubular arm, (here shown as consistingof two telescopic sections 5 6,) although it is to be understood that agreater number of sections may be employed. To hold the sections asadjusted one relatively to the other, I provide a spring-pressure devicebetween the inner section and outer section. This spring-pressure deviceconsists of two segmental springplates 7,which engage with their edgesagainst the outer surface of the inner tube 6 and at their centralportions with the inner surface of the tube These spring-plates areprevented froni longitudinal movement on the section G b v engaging attheir ends with annular iianges 8 on said inner section or tube. I haveshown in the drawings the socket 9 for an incandescent lamp as securedto the end of the inner section 6. It is to be understood, however, thatthe device may be used for supporting any other form of lamp. The arm orsupport has a double universal con nection with a cup-shaped base 10,designed to be secured to a ceiling or a wall, and within thiscup-shaped base is an ordinary rosette 11 for electrical wireconnections. The supporting-base 10 is provided with oppositelyextendedlugs or ears 12, provided with perforations through which fasteningscrews may pass. Extended in opposite directions and at right angles tothe lugs 12 are broader bearing-ears 13. By reference to the dotted linein Fig. 1 it will be noted that the bearing-surfaces of the ears 13 areon a higher plane than the bearing-surfaces of the lugs l2. This is toadapt the device to t snugly against an uneven ceiling or wall-'that is,when the screws are passed through the lugs l2 the ears 13 will be drawnclosely against the plaster of a ceiling or wall and be pressed somewhatinto the same. The base 10 terminates in a socket-section, consisting oftwo portions 14 and 15, having outwardly -extended lugs through whichclamping-screws 16 extend, and to cause a yielding pressure of thesocket upon the ball or inner member 17 at the joint I placespring-yielding wasliers 18 between the heads of the screws and theadjacent lugs.

The suspending or support-ing arm connects with the socket member of thejoint consisting of two sections 19 and 20, in which the ball or innersection 21 turns. These sections 19 and 20 are provided withoutwardlyextended lugs through which fasteningscrews 22 pass, andspring-yielding washers 23 are placed between the heads of the screwsand the adjacent lugs for the purpose above described. To produce asufficient friction between the ball or inner members and the socketmembers of the joints, the said ball or inner members instead of beingmade solid are in the form of a central hub having radial wings which attheir outer edges bear against the inner surfaces of the socket members.The two ball members are connected together by a tube 24, through whichthe electric wires may pass.

In operation it will be seen that thearm may be turned from a verticalto a horizontal position to any desired angle, reaching-that of a rightangle to its normal position. In turning the device to an angle the ballmember 17 will be turned in its socket, permitting IOO the arm to beturned at an angle of about forty-tive degrees. Then the arm may beturned on the ball 21 to an angle of ninety degrees. These angles arerespectively shown by the dotted lines w and g/ in Fig. l.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. A lamp-hanger, comprising a base, an arm, and auniversal-joint'connection between said arm and base, the jointconsisting of a socket member and an inner member comprising a hubport-ien and radial wings for bearing against the inner surface of thesocket member of the joint, substantially as Specified. g

2. 'In a lamp-hanger, abase, an arm, a uni# versal-joint connectionbetween the arm and base, said joint consisting of a socket member andan inner member comprising a hub portion and radial wings, and thesocket member consisting of two sections having outwardly-extended lugs,clamping-screws engaged with said lugs, and spring-yielding Washersbetween the heads of the screws and 25WY the adjacent lugs,substantially as specified.

3. In a 1an1p-hanger, an arm, a base with Y which said arm connects,perforated lugs extended outward from said base, and ears extendedoutward from the vbase at right angles to the lugs, the'bearing-surfacesof said ears being on a higher plane than the bearing-surfaces of thelugs, substantially as specied.

4:. In a lamp-hanger, an arm consisting of telescopic sections, anges orcollars formed Y35V Y on the inner end of the inner section, and

.transversely-curved spring-plates arranged between said collars andforming a spring pressure between the telescopic members, the

edges of the spring-plate engaging against 4d the inner section,substantially as specified.

In testimony whereof I have signed my naine to this specification in thepresence of a Y Y two subscribing witnesses.
